• 20

An isosceles triangle has an angle that measures 40 degrees. 70 and 100 are other angles could be in that isosceles triangle

Solution:

Given that isosceles triangle has an angle that measures 40 degrees.

If a triangle is isosceles then it has 2 identical angles and the third different one.

Let the two identical angles be "a"

We know that sum of angles in a triangle is 180 degree

a + a+ 40 = 180

2a + 40 = 180

2a = 180-40

a = 70

Thus the two identical angles are 70 degree and 70 degree

Now let the identical two angles be "40" and the third angle be "a"

Now sum of angles = 180 degree

40 + 40 + a = 180

80 + a = 180

a = 100

Thus the third angle in this case is 100

70 and 100 are other angles could be in that isosceles triangle

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
